The distribution of euphausia snperba in the prydz bay region was very patchy , its abundance was higher in the slope area ( the pelagic area between the isobaths 1000 m and 3000 m ) than the open sea area ( the pelagic area beyond the 3000 m isobath ) 大磷虾在普里兹湾海区的分布呈斑块状。分布趋势是陆坡区(在1000和3000米等深线之间的海区)各站的丰度普遍大于深海区(大于3000米深度的海区)各站的丰度。
Most if not all species live in patchy habitats . this has become increasingly true because of landscape fragmentation throughout the world . the set of local ( patch ) populations of a species in spatially discrete habitats may be called a metapopulation 随着全世界范围内景观破碎化的加剧,大多数物种都逐渐生活在斑块状生境中,这成为一个不争的事实,分布于不连续生境中某物种的一系列斑块(局部种群)就称之为复合种群。
In chapter 5 , the method of combining the exact target state parameter fused by multi - sensor tracking data and the tendency of the whole tracking data to detect outliers is proposed . distributed multi - sensor fusion method can resolve the problem of patchy detection efficiently and quickly 该方法能解算出完整的、高精度的、连国防科学技术大学研究生院学位论文续的弹道,并能给出主要系统误差的估计,提高弹道跟踪数据跟踪精度
The effect of patchy - distribution of mangrove on birds was complexity . its increased habitat heterogeneity can attract some different type birds . however , its result of fragmetating mangrove habitat decreased the species diversity and population size of birds 红树林斑块分布对鸟类影响比较复杂,一方面斑块生境异质性高,可以吸引不同类型鸟类,另一方面又导致了红树林生境的破碎化,减少了鸟类的活动空间,从而导致鸟类种类和数量的减少。
The temporal and spatial dynamics of a single species metapopulation is modelled by a model . the stability of spatial distribution of the population and relationships between the stable patchy distribution and migration rates and finite rate of growth of subpopulations are also investigated . finally measures to boost the growth of total population are presented through the model and analysis of the model 通过模型模拟了呈一般缀块分布的单种种群的时空动态.讨论了种群空间分布的稳定性及稳定缀块分布与种群在缀块间迁移率和子种群增长率之间的关系,并由此提出了促进全局种群增长的措施
The species can only be found at altitude 400 - 1000m in the beauty spot of bei jiu shui of mountain lao , and lives in patchy habitats . the habitat is located at the shade slope or semi - shade slope where the forest coverage was developed well and the sunlight and soil humidity can meet the needs of the species 调查结果显示,目前青岛百合集中分布地仅次于崂山北九水以南,海拔400 1000m的区域,植物一般生长于阴坡或半阴坡的森林中,说明青岛百合的生长发育既需要较为充足的水分供应,又必须保证足够的光照。
